Forest Loss by Country

Forests are the dominant terrestrial ecosystem of Earth and are distributed across the globe.Forests account for 75% of the gross primary productivity of the Earth's biosphere and contain 80% of the Earth's plant biomass. via

World Ecoregions & Biomes

World Ecoregions This new map offers a depiction of the 846 ecoregions that represent our living planet. Ecoregions are ecosystems of regional extent. These are color coded on this map to highlight their distribution and the biological diversity they represent. This new map is based on recent advances in biogeography - the science concerning the distribution of plants and animals. The original ecoregions map has been widely used since its introduction in 2001, underpinning the most recent analyses of the effects of global climate change on nature by ecologists to the distribution of the world's beetles to modern conservation planning. In the same vein, our updated ecoregions can now be used to chart progress towards achieving the visionary goal of Nature Needs Half, to protect half of all the land on Earth to save a living terrestrial biosphere. World Biomes There are 14 terrestrial biomes. Seven are forested and 7 are not forested. Plant communities in the same biome can ap

Lights On & Lights Out

The comparative illumination of the night sky between 2012 and 2016. Areas of new nighttime light are shown in blue areas of extinguished nighttime light are shown in magenta. Light on (blue) Some reason for new nighttime illumination is suburban growth rings around existing urban centers, newly built transportation lines, the electrification of rural areas, or wellhead fires at new petroleum extraction sites. Light out (magenta) Some reasons for extinguished nighttime illumination are the collapse of population or infrastructure due to war or social upheaval, the contraction of populations from economically struggling areas, or preventative measures taken to reduce nighttime light pollution.

India: Old Lights & New Lights

At the base of the Himalayas, vast expenses of new nighttime light emerge over the past 5 years, surrounding and connecting areas previously illuminated. In the United Arab Emirates and parts of Oman, distinct stretches of new highway are etched out of the desert, shining brightly now where there was just nighttime darkness a few years ago. In southern parts of India, urban growth is especially apparent. Whole growth rings emerge from around the urban centers, carving out new areas of nighttime illumination. Source:

Global air pollution levels (2013 - 2014)

All levels are based on an average of the top 10 most polluted cities in each country. India is by far the worst with 134 fine particle matter 2.5[ug/m] and Sweden had the lowest levels at 7.2. Most of the data were collected in 2013 and 2014 with a few countries only having data available from 2009. Other countries, especially in Africa, did not have any data.

Deaths From Asbestos-Related Disease by U.S. county

Although the U.S. has regulated asbestos exposure since 1971, deaths from malignant mesothelioma have continued over the past two decades. The disease, which can develop after inhaling asbestos fibres, caused or contributed to more than 45,000 deaths in the United States between 1999 and 2015. Via

Adopt the Planet

64,000 locations on Earth available. Which one will you get? NASA invites you to help us celebrate Earth Day 2017 by virtually adopting a piece of Earth as seen from space. Your personalized adoption certificate will feature data from NASA’s Earth-observing satellites for a randomly assigned location. Print it and share it, then explore other locations with our interactive map and get even more Earth science data from NASA’s Worldview website. Via

Vegetal Waste (Final Consumption by Country)

The vegetal wastes are secondary products from agricultural activities which mostly remain chaotically into the soil. As result vegetal waste disrupts the technological process. Generally, the secondary products are unvalued because of lack of financial resources or means work of farmers. Many farmers have this behavior, especially they who own small agricultural areas. The cellulosic content of waste i.e. straws, corn cobs represents an important source of energy which must be used. Referring to this noted that exist an energetic rich from cereals grains and from the ratio of main production and secondary ones. The issue of unused wastes is neglect for this resource. These aspects characterize as we said smaller farms which are numerous. The loss is magnified even more with how these products can be obtained from ethanol, butanol or other compounds that may be fuel or raw materials for chemical industry. Worldwide, specialist research has shown that the use of bioethanol inste

Mapping the human impact on the Great Lakes

Chris Brackley It’s no secret that the Great Lakes are suffering tremendous ecological strain — Lake Erie was even pronounced “dead” for a time during the 1960s because of an overload of phosphorus from municipal waste. Back in 1615, though, when the entire region was pristine and explorers Samuel de Champlain and Étienne Brûlé gazed out together from Lake Huron’s shores, they dubbed it lamer douce, “the sweet sea.” Today roughly one-quarter of Canada’s population and a 10th of America’s population drink from the Great Lakes basin; the beleaguered lakes alone hold more than a fifth of Earth’s freshwater. The Great Lakes Environmental Assessment and Mapping Project — a group of about 20 American and Canadian researchers and environmentalists — produced the data for the map above, which illustrates the cumulative impacts of human activity across the Great Lakes. It speaks volumes at a glance. David Allan, team lead for GLEAM’s project and a professor at the University of Michig

The Water Quality of U.S. Streams and Rivers

This mapper provides results from the largest-ever assessment of water-quality changes in the Nation's streams and rivers. More than 185 million water-quality records from over 600 Federal, State, Tribal, and local organizations were screened as part of this assessment. Tracking changes in stream quality and investigating the reasons for these changes is crucial for informing management decisions to protect and sustain our valuable water resources. The mapper shows stream trends in water chemistry (nutrients, pesticides, sediment, carbon, and salinity) and aquatic ecology (fish, invertebrates, and algae) for four time periods: 1972-2012, 1982-2012, 1992-2012, and 2002-2012.
